How to make Chocolate & Vanilla Marble cake

Marble Cake:

Ingredients:
▪ 300g Margarine
▪ 250g Sugar
▪ 1 tsp Vanilla extract/essence
▪ 5 Eggs
▪ 380g Plain flour
▪ 4Tsp Baking Powder
▪ 3 Tbsp Cocoa Powder


Method:
1. Pre heat the oven to 180ºC/350ºF. Grease a rectangular/square tin and line with a greaseproof paper or simply dust with a thin coat of flour.
2. Place the margarine in a bowl and beat till smooth then stir in the sugar and vanilla extract till thickened and smooth.
3. Add the eggs one at a time whisking vigorously each time before the next.
4. Sift the flour and baking powder into the butter and egg mixture and mix well until all the flour is not visible.
5. Scoop off 2/3 of the cake batter onto a baking tin. Add the cocoa to the remaining cake batter to make the chocolate batter. Add to the white batter and using a spoon swirl the two mixtures to form the marble effect.
6. Bake for about 25 minutes when using a large rectangular pan or until the cake has browned on top and firm when pressed at the centre. You can also check by dipping a small knife or toothpick at the centre or the cake, which should come out dry when ready.
7. Leave to cool in the tin for about 10 minutes then transfer to a wire rack. Divide accordingly and dust with icing sugar.
